Compact Bone forms the dense outer layers of all bones. It is composed of many parallel, longitudinal column-like structures called Haversian Systems, cemented to each other. Haversian canals are connected to each other by Volkmann canals. In each Haversian system, several concentric layers (Lamellae) of bony matrix encircle a longitudinal central canal (Haversian Canal). This canal carries blood vessels and nerves Lacunae containing osteocytes occur in a layer between two lamellae. The medullary cavity or marrow cavity within diaphysis of long bones contains fatty yellow bone marrow in adults.
